problems with pktsetup

hallo all,

Using SuSE-9.2 I have read all stuff, here in the ML too.
And beliefe me, I tried more than 50 hours to help me myself.

Have my (new) self made Kernel 2.6.8-24.11-6 patched with
packet-2.6.8.patch, compiled and installed. So there is
packet-writimg in the kernel (Modul pktcdvd)
The Modul udf is aktiv too.

After this I compiled and install udftools-1.0.0b3.tar.gz
and patched it with udftools-1.0.0b3.patch.bz2
The patch for pktsetup.c was done well.

In /dev I found /dev/pktcdvd
I did a  mknod /dev/pktcdvd0  b 97 0
I wrote into  /etc/modprobe.conf : alias block-major-97  pktcdvd

lsmod shows the moduls udf and pktcdvd

My cdrom = /dev/hdb, dvd (no burner) = /dev/hdc,
and my cd-burner (cdrw - ATAPI) is /dev/hdd
/media/cdrecorder is a link to /dev/hdd

I could format a disc (cdrw) with "cdrwtool -d /dev/hdd -q" well
(I have for MSWindows "InCD" too and could use the formated
cdrw with InCD, all ok)

adda:~ # pktsetup
pktsetup /dev/pktcdvd0 /dev/cdrom       setup device
pktsetup -d /dev/pktcdvd0               tear down device
adda:~ #

And now my problems: here some experiments of me:

  adda:~ # pktsetup /dev/pktcdvd0 /cdrecorder
open packet device: No such device or address

  adda:~ # pktsetup /pktcdvd0 /dev/hdd
ioctl: Inappropriate ioctl for device

  adda:~ # pktsetup /dev/pktcdvd0 /dev/hdd
open packet device: No such device or address

  adda:~ # pktsetup pktcdvd0 /dev/hdd
ioctl: Inappropriate ioctl for device

adda:~ # pktsetup /dev/pktcdvd0 /cdrom
open packet device: No such device or address
adda:~ #

What is here wrong? I can't setup my writer.

In /usr/src/linux/Documentation/cdrom/Packet-writing
is written:

Setup your writer: # pktsetup dev_name /dev/hdc (my=hdd)

What is the correctly "dev_name"?
I didn't find a sample for "dev_name". And you can see,
with my experiments i had no luck. And without a correct
setup for the writer I can't mount the writer too.

Scripts I found couldn't help me (why?)
I use udev and hotplug
The /dev/hdd (cdrecorder) isn't mounted with subfs
Tests in /etc/fstab didn't help.

In /etc/init.d and /etc/default there are no inscriptions
for udftools.

Only I didn't install the packet "udf-0.9.8.tar.gz
But I think, that's ok, or?

My cdrecorder is no scsi-driver, its ide-cd
But it can format, so I think there is no problem

Also I'll tell you, that everytime by the experiments
there was a formated udf-cd in the cdrecorder.

I hope, now you know all you need to help me.

For your help here many thanks
Sorry for my (bad) english, don't be angry about

Best regards
yours Bernd
